a kitten and a basket has a mass of 3 kg . A hamster and a similar basket has a mass of 1.4kg . the mass of the kitten is 5 times the mass of the hamster .a. wh

kitten = x ,hamster = y and baskest = z

x+z = 3 kg
y+z = 1,4 kg

z = x- y = 3 kg - 1,4 kg = 1,6 kg

x+y = 4,4 kg - 1,6 kg = 2, 8 kg

x = 5y 
5y +y = 2,8 kg
    6y  = 2,8 kg
      y = 2,8 kg /6
      y = 0,47 kg
x = 5y
   = 5 * 0,47 kg
   = 2,35 kg 

a. mass off  hamster = 0,47 kg
b. mas off kitten = 2,35 kg

bonus...mass of basket = 1,6 kg
